The $100,000 per couple Trump anniversary party at Mar-A-Largo was still held over the weekend, on day 1 of the government shutdown Trump caused. Now, Trump did at least adjust his plans to not attend it, but the rest of the folks partied on. Trump typically has has the taxpayers shell out a fortune on his travel expenses for him to pleasure himself out on the golf course on weekends, but he did at least just stay in DC this one weekend. Active all active-duty members of the military are to continue their duties, but won't get paid until after the shutdown is resolved. Maybe some of that money raised could go to the folks in the military.

Thank you, HisLegacy, for those articles. This is what is says about the restaurant the Dems went to:
Now sure, that is pricy in comparison to Applebees or what have you, but sure is FAR less than what was spent on dinner at Trump's party.
